The Anti-Corruption Bureau (ACB) has said it has concluded investigations in the case involving former president Peter Mutharika on alleged abuse of his duty-free benefits.

ACB Principal Public Relations officer Egrita Ndala confirmed of the development in an interview with one of the local daily papers.

According to Ndala, the graft-busting body is currently working on a strategy to ensure progress in the case with the Director of Public Prosecution (DPP).

“The ACB is currently liaising with the Director of Public Prosecutions on how best to move forward with the case due to the fact that both the police and ACB were investigating issues of the former president, but focusing on different areas.

“The police were focusing on cement and ACB focused on other items that were imported using the former president’s TPIN,” said Ndala.

Earlier this year, the Bureau failed to interview Mutharika on the matter after he opted to remain silence on the matter.

Since then there has been blackout on the case.
